Index exceeds array bounds.

I try run this code for keep use remaining useful life, but it doesn't work.

BOP = readtable('auxiliary_equipment.csv');
head(BOP)

%%Divida os dados do subsistema auxiliary equipment de treinamento e
% um conjunto de dados de validação para avaliação posterior de desempenho.

rng('default') 
numEnsemble = size(BOP);
numFold = 2;
cv = cvpartition(numEnsemble, 'KFold', numFold);
trainData = BOP(training(cv, 1),:);
validationData = BOP(test(cv, 1),:);

%
varNames = string(BOP.Properties.VariableNames);
timeVariable = varNames{4:6};
conditionVariables = varNames(7:12);
dataVariables = varNames(1);

%
nsample = 10;
figure
helperPlotEnsemble(trainData, timeVariable, ...
[conditionVariables(1:2) dataVariables(1:2)], nsample)

Index exceeds array bounds.

I'm not even going to try until you attach 'auxiliary_equipment.csv'.
